Converting Sound and video from 24 to 25 in Cinematools

Hi again!
I have a 24 fps audio and video file and have conformed it in CINEMATOOLS (v4.5.1) to 25 fps. So far I can heard the audio is speeded up too and keeps sync with image, and without considerable changes.
Is it possible? Has anybody tried this before? Is there something I should consider about the audio quality?
Thanks a lot!
Ignacio

A lot of programming originated at 24p is simply sped up to 25p for video playback. As you've noted, the duration is shorter and the audio is pitch-shifted slightly.

Michael Gissing has repeated answered the question on how to compensate for the audio-pitch shift on this forum -- see one such answer in this thread:
